According to sources, Leo got the heads up from gal pal Reese Witherspoon. Sheltering R-Patz from the severe sh*tstorm of Kristen Stewart's cheating scandal, Reese thought it'd be a nice idea to put the two of them in touch.

One source divulges details on the guys new bromance, saying:

"Leo has been one of Rob's role models for years, and Rob was totally taken by surprise when Leo called him. He invited Rob along on a getaway he's planning when he's in Puerto Rico for the wrap party on the movie he's producing, Runner, Runner. Leo wants to book a mansion at a secret location on the coast so he and his pals can party in private. He's kept an eye on Rob's career ever since people started calling him the next Leonardo DiCaprio. Leo figured it would be great for him to hang out with a bunch of laid-back guys. Leo joked they could compare baseball cap collections - and told Rob before he knew it, he'd be dating a model, just like him!"

Ha! Welp… Robert could definitely pick up any model he wanted, that's for sure!

But we're so excited about this blossoming friendship! And it's true — fans haven't gone crazy over a Hollywood hottie like this since Leo's icy hand was snapped off in the Atlantic Ocean!

Perez, this is old old news and not true. If anything I bet Leo is thinking he'd like to go out with Kristen.He went to the "Welcome to the Riley's" premiere. ROB DIDNT!! Giovanno has a lot of friends. I saw him dining with Mel Gibson the other night.

This has got to be one of the dumbest stalkerazzi stories out there. Seriously??? I highly doubt Leo compared baseball hat collections with Rob. You make them sound idiotic. Maybe you should just focus on other pursuits.

Everything that comes off these pages is nothing but lies. These so called "sources" are non existent, but to tell the truth wouldn't be exciting, would it? Rob has already said that none of the crap printed is true but you vultures just keep on, don't you? When will you decide enough is enough? You're all becoming a joke in your own right. What a minute, wasn't Perez the one who went on Ellen a while back, promising to not write anymore untrue, hurtful articles that negatively impact lives, instead, writing about subjects that matter and DON'T hurt people. Looks like he's failed miserably and has become a joke just like all the other tabloids.

A new Bill Cosby accuser's story of how he allegedly sexually assaulted her after drugging her drink is horrifying.

According to Patricia, -- who decided to keep her last name anonymous -- Bill invited her to a dinner party in 1978 after they met at a conference... a dinner party that ended up just being the two of them:
